HOW TO FIT RUNNERS - INTERNAL BLUM TANDEMBOX -
This page shows the quickest and easiest way to mark out and fit runners for your drawer box.
A video of each procedure is also available on the product page.

How to fit shallow inner Blum Tandembox Antaro drawer runners With the drawer box assembled, you are now ready to fit the packers and runners

NOTE - If you are fitting the internal drawer behind a tall Drawerfront, ignore the packing block segment and follow all other instructions.

When fitting a 3 pack or Spacetower, Start at the bottom and work your way up from there.

  • The 25mm packer blocks supplied with your kit go on the hinge side runner, and allow the drawer to clear the hinges
  • Normally 3 to 4 packer blocks are fitted on each hinge side runner
  • Bottom Drawers -Tandembox runners can lie directly on the base of the unit and will operate normally.
    This makes installation of the bottom drawer very quick and easy - just lay the runners on the base in the correct position,
    and attach straight into the side with the screws provided. (This assumes any hinges are set high enough not to interfere)

Decide on the position of your internal drawers using the following factors..
  • Equally space them in the unit if you have 3 or 4.
  • Space them in the unit depending on what will be stored - eg cereal boxes/tins/etc
  • Mark where the bottom of each drawer will go in pencil, and proceed if there are no issues with hinge positions or space restriction.

  • With the drawer position decided, and the bottom position marked, we can now mark the runner screw hole positions
  • PLEASE NOTE.. Mark the hole positions for each runner BEFORE fixing the packing blocks to the hinge side runners
  • On both sides, from the bottom mark position go up 33mm and mark a line inside the unit using a set square
  • Go as far in as possible with this line, ensuring it is square to the front of the unit

  • Mark the hole positions now for each side BEFORE fitting packing blocks
  • Set the FRONT of the runner 5mm back from the front edge of the unit, and line the holes up with the line marked into the unit
  • When marking hole positions, always use the MIDDLE hole in each group of three on the runners.
  • Mark 3 to 5 hole positions onto the line, front middle and back (depending on runner length)

  • Start the holes off using a screw. Do not go all the way in, just start it off
  • Do this for BOTH SIDES

  • Now attach the packing blocks on to the hinge side runner.
  • MAKE SURE TO position the clearance hole on the packer block over the same 3 MIDDLE holes on the runner

  • Finally, fit runners ON BOTH SIDES using the screws supplied
  • Make sure the screws do not go in at an angle, as this can snag the drawer

  • With the runners fully retracted inside the unit, lay the box onto the runners approx 25% of the way in
  • Push the box downward and in toward the back of the unit
  • The box should click into place in the runner and locate itself
  • Installation is complete


    TO REMOVE THE BLUM TANDEMBOX DRAWER FROM THE RUNNERS -
    Pull the drawer all the way out
    Hold each corner at the front
    Pull up the way and wiggle the drawer at the same time
    Don't worry, it won't break, it will just free the drawer
